Application filed November 18, 1920. Serial No. 425,022.

T 0 aZZ whom it may concern:

Be it known that I, MARTIN JELALIAN, a citizen of the United States, residing at the city of Cranston, in the county of Providence and State of Rhode Island have-invented certain new and useful Improvements in Manually-Operated Bufiing Devices for the Inner Faces of Rings, of which the following is a specification.

The object of this invention is to improve the buffing manner of the inner faces of rings, providing a manually operated butting device operated by crank shafts.

The parts of the device are so arranged that the same are readily and safely operated and by the operation of the same an unusual amount of work may be obtained.

The detailed description of the invention is illustrated in the accompanying two sheets of drawings forming a part of this specification in which:

Figure l is a side perspective view of the device. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is an enlarged side view of a strap holder clip. Fig. is an enlarged side perspective view of a casing device for setting rings, to buff the inner faces of the same therein. Fig. is a front view showing the casing device as mounted upon the spindle and engaged with operating strap connections, and Fig. 6 is a top plan view of Fig. 5.

Referring to thexdrawings -a designates a bench. Arranged uponthe top of said bench a are standards b, b each provided with a shaft Z)- and a spindle Zs at the free end thereof.

Said spindles Zc, Zc have flannels secured thereon and rings -6 mounted upon the same closely one on the other.

Passing over of each set of said rings mounted upon the spindles /c, are operating straps e having their ends provided with clip holders g 9 and secured to the ends of flat portions 1', 9- projecting outwardly from oscillatory shaft Z which is arranged longitudinally to the bench a and extending forwardly to the standards Z), Z). The shaft E is provided with a crank at each end thereof and operated by shaft -E- which is also provided with a crank at each end of the same and extending forwardly to the oscillatory shaft L.

The shafts Z and Z are connected together by connecting arms -n, n which extend between the ends of said shafts and each provided with an eyelet at each end thereof and loosely mounted upon the end portions of said shafts Z and Z. A'collar is secured upon the each free end portion of saidshafts and designed to keep said connecting arms -n, n in position upon the end portions of said shafts.

' rranged longitudinally to the bench a/- are vertically extending supports e, 6, having their lower ends secured to the bench and supporting shafts Z and Z upon their upper ends. Mounted upon said shaft is a pulley r which is provided with a belt connection ]c passing over pulley is mounted upon upper shaft -a lVhen shaft Z operates, it will impart a backward and forward oscillatory movement to the shaft Z. Thus each strap e" of the spindles Z k will engage to perform the buffing operation by a backwardly and forwardly operating movement.

Each clip holder g"- is provided with coil pull-springs -q, 9- having one of their ends secured to the rear ends of said clip holders q and the other ends provided with snap-hooks -9 g and secured to the ends of the flat outwardly projecting portions -7', 13- of the shaft -Z.

Each standard b, bis provided with a belt Z) to drive the same and having a section -77/' which is integral with the spindle shaft and provided with means to be raised and lowered.

It is preferable to have the standards for this purpose in the form as shown.

Removably secured upon the free end portions of the spindles -70, /c' of the standards b, bare collars o which are adapted to keep the straps -0 cin their position upon the spindles -7c, 7:.

The clip holder 9 comprises a base plate member provided with two vertically arranged integral pins -66, a having a transversely extending shaft a. upon which is mounted a snap plate member and having coil-spring connections p and p therebetween.

In Fig. 4 is shown a ring casing device which is designed to receive setting rings -a within the same and adapted to be mounted upon the spindle k and engaging with stra connections in the manner as shown in *igs. l and 2 and Figs. 5 and 6. A removable collar o is secured upon the end having standards secured upon the top of the same and having spindles provided with flannels thereon, a horizontal crank shaft forwardly to said standards and arranged longitudinally to said bench and having fiat outwardly projecting portions arranged op posite to thespindles of said standards, an operating. strap for each of said spindles and passing over each of said spindlesand having clip holders at the free ends thereof and connected to the outwardly projecting portions of said shaft, means to operate said shaft andto impart backward and forwardmovement to said straps.

2. In combination with a .bufling bench having standards secured upon the top of the same and having spindle shafts provided with spindles, a crank shaft provided with sets of ioutwardly projecting portions extending forwardly to said standards and arranged longitudinally to said bench, a hori zontal crank shaft forwardlyto said shaft and adapted to impart an oscillatory move ment to the latter, a connecting arm between the ends .of said shafts each provided with an eyelet at each end thereof and loosely mounted upon the end portions of sa d shafts, vertically arranged supports for said shafts and having secured to said bench, means to operate said shafts and collars secured upon the end portlons of thesame to keep the connecting arms in positlons upon the end portions of said shafts.

' 3. In combination with a buffing bench,

having standards arranged upon the top of the same and having spindle shafts, an"

of vertically arranged integral pins sup porting a shaft and having" a snap plate member mounted upon the same, coil spring connections forwardly and rearwardly of said vertically arranged pins between said base plate member and snap plate member,

and coil spring connections from the rear ends of said clip holder to the fiat outwardly projecting portions of said oscillatory crank shaft. 7

4:. In combniation with a buffing bench having standards arranged upon the top of the same and provided with spindles, an oscillatory crank shaft forwardly to said standards and having outwardly projecting flat portions arranged opposite to thespindles of said standards, a ring casing'device for said spindles each comprising two sec tions connected together and adapted to receive setting rings therein and mounted upon said spindles, an operating strap, passingover said ring casing and having a clip holder at each end'thereof and connected to the outwardly projecting flat portions of said shaft, and a collar secured uponthe end portion of each of said spindles of said standards to keep the operating straps in position upon said ring casing.

Intestimony whereof, I afiix my signature in presence of two witnesses.
